WINDOW-CHAIR.

SPECIFICATION forming partof Letters Patent No. 759,629, dated May 10,1904. Application filed October 21,1903. Serial No. 177,849. (No model.)

To all whom it may concern.-

Be it-known that I, LOUIS W. N munonrr, a citizen of the United States,residing in New :York, in the county of New York and State of New York,have invented certain new and useful Improvements in W i ndow-Chairs, ofwhich the following is a specification.

This invention relates to window-chairs, and is designed for usepreferably in connection with windowwork-such, for instance, as cleaningthe glass or painting the woodwork thereof.

In working about a window it is customary to sit on the window-sill andsupport ones self by holding onto the window-frame or the rails of thesash, which is not only inconvenient but also dangerous, in that onehand must be employed in holding onto the window while the other handcarries on the work, and there is also the danger of losing ones gripwhile carrying on the work, causing the person to overbalance and fall.Straps are sometimes used to fasten the body to the window-frame, butthere is the danger of the strap becoming unhooked, or if the strain istoo great the strap will sometimes give way, and for this reason thisform of safeguard is objectionable. It has also been found to bedangerous in that while persons are either hanging clothes from a windowon a pulley-line or in shaking or dustinggarments or rugs they sometimesslip or they otherwise lose their balance and fall out of the window.

The object of this invention is to provide a guard to prevent fallingout of the window, either when sitting on the sill thereof or whenleaning out.

A further object is to provide a support to the back when sitting on thewindow-sill on the outside of the window.

A still further object is to provide a device which can be collapsedinto a small bundle at will.

In carrying out these objects I provide a framework which is securableto and detachable from the window, preferably on the inside of thecasing, and this frame serves as a guard against which to lean or abaclerest when sitting on the sill.

In the drawings accompanying and forming a part of this specification,Figure 1 is a perspective view of a window-sill, a portion of the stile,and the window apparatus located in place. Fig. 2 is an elevational viewof the same, and Fig. 3 is an additional elevational View showing theapparatus partially collapsed.

' Similar characters of reference indicate like parts throughout thefigures.

I provide in the first instance a pair of braces, which may bedesignated in a general way by 2 and 3 and which may comprise uprights 4and 5, to the upper and lower ends of each of which are securedcross-pieces 6 and 7, 8 and 9. Proceeding downwardly from thesecrosspieces are two feet 10 and 11, the former of which is the shortestand is designed to rest upon the subsill 12, while the latter, which isa littlelonger, rests down on the main sill 15. The feet 10 are unitedby a cross-piece 14, which is preferably provided with a hinge aboutmidway of its extremities. This crosspiece is also provided with stops16 and 17 for purposes which will be later mentioned. Proceedingupwardly from the cross-bars 7 and 8 are uprights l8 and 19 and 20 and21. To the uprights 18 and 20 are secured laterally-extending arms 22and 23, to each of which is hinged or pivoted a grimnng-plate 2 1 and25, respectively, provided in the present instance with rubber steps orcushions 26, and these gripping-plates are designed to bear against theinside of the framework 27 of the window-for instance, as seen inFig. 1. The uprights 19 and 21 are each provided with laterally-extendedpieces 28 and 29, to each of which is pivoted a cross-bar 30, havingarms 31 and 32, through which the pivots 33 and 34 pass. This cross-baris also hinged, as at 31, midway of its ends, and one of the hingedportions is provided with a tongue 35, over which may he slipped a ring36 for the purpose of preventing the cross-bar 30 from buckling at thehinge when in use. This cross-bar 30 may either be extended to theposition shown in the full lines when it is desired to use the device asa back-rest when sitting in the window or else it may be overturned, asshown in the dotted lines, and allowed to rest in the lugs 37 and 38, soas to form a body-bar when one is leaning out of the window. Also hingedto the cross-pieces 7 and 8,11ereinbefore referred to, are braces 39 and40, which when the device is in place bear against the stops 16 and 17and hold the entire structure in place.

One of the main features of this device is its collapsibility, wherebyit may be closed into a compact form, and this is clearly shown in Fig.3, Where the device is shown as partly collapsed. In this figure thebraces 39 and 40 have been moved, for instance, to the position shown indotted lines of Fig. 2, and the crossrod 14 has been uplifted to theV-shaped position, .as shown. The cross-bar 30 has also been lifted tothe position shown in dotted lines in Fig. 1, and the ring 36 havingbeen removed from the tongue 35 this rod is also buckled to the positionshown in Fig. 3. This arrangement permits the side constructions to bedrawn together. At the same time the gripping-pieces 24 and 25, whichare pivoted to the portions 22 and 23, as at 41 and 42, may be thrownagainst the upright pieces 18 and 20, so that that they will not projectin the way when the device is collapsed. The method of closing thesegripping pieces against the uprights 18 and 20 is shown in dotted linesof Fig. 1 at 43.

It will be seen that the structure thus described provides a safeguardwhich prevents falling out of the window and which may be used either asa back-rest when seated in the window or a guard against which to restwhen standing on the inside of the window.

It will be understood,of course,that the illustration herein is simplyto picture my invention and that the precise arrangement of parts or theprecise construction shown is in no wise intended to limit thisinvention, and I reserve the right to vary this construction and tosubstitute or omit certain of the parts, so long as I produce aneffective, efficient, and durable structure for the purposes designed.

Having thus described my invention, I claim 1. A window-chair comprisinga pair of uprights; a cross-bar by which to unite them; anothercross-bar adapted to form a guard or a rest; both of said bars being insections, and the whole adapted to be collapsed into compact form.

2. A window-chair comprising a pair of uprights; a cross-bar connectingsaid uprights and provided with a hinged joint; means for positioningsaid uprights at right angles to the bar; a cross-rail carried at theupper end of said uprights; a device to hold said uprights against thewindow.

3. A window-chair comprising a pair of uprights; a hinged bar connectingthe same;

means carried by the uprights and cooperating with said bar to hold saiduprights in a position substantially at right angles to said bar;devices carried by said uprights for holding the same in place to thewindow-frame; and a pivoted hinged bar adapted to operate either as arest or guard also carried by said uprights; the whole, through themedium of said hinge, being adapted to be collapsed into compact form.

4:. A window-chair comprising a pair of uprights; a pair of grippingdevices pivoted to the upper end thereof; a cross-bar for uniting saiduprights; a resting-piece carried by said uprights; said resting-piecebeing pivoted to said uprights and adapted to be-extended into place;and means between said uprights and said cross-bar and adapted to holdthe frame in position when seated in the window.

5. A window device of thecharacter specified, comprising a pair ofuprights; a pair of grippers hinged to the upper ends thereof; a

cross-bar uniting said uprights and comprising two hinged portions; aresting-bar carried by the upper end of said uprights and provided witha hinge; a pair of braces carried by the uprights and adapted to restagainst said bar, whereby to hold the uprights in position in the frame.

6. A window-chair comprising apair of uprights; a two-part bar hingedtogether and joining said uprights; a lug carried by each hinged part; abar carried by each upright and adapted to bear against each lug; a pairof grippers carried by said uprights and adapted to bear against thewindow-sash of the window-frame; a hinged cross-piece pivoted to saiduprights and adapted to be moved in any position thereon; said hingedbar and hinged cross-piece being adapted to buckle, whereby to collapsethe entire structure. 7
